Operation notes (use)
Before working on electrotechnical components and parts, the
devices must be de-energised and protected against restarting.
This work may only be carried out by adequately trained specialist
personnel.
If unexpected vibrations occur on the device or if the device is
exposed to vibration loads from the outside, the machine must be
switched off immediately and the cause of the vibration must be
eliminated before restarting.
Overhaul
Main ten ance sche dule
NOTE:
The maintenance intervals depend very much on the indi-
vidual operating conditions. The intervals given below shall be con-
sidered as starting values which should be shortened or extended
as appropriate. Particularly heavy duty operation,
such like high
dust loads in the environment or in the process gas, other contam-
inations or in gress of process material, can make it necessary to
shorten the maintenance intervals significantly.
